The defect
Daimler Trucks North America LLC (Daimler) is recalling certain model year 2008-2015 Freightliner 114SD, Cascadia, M2 Business Class, Sterling LT8500, and Thomas Built Buses Saf-T-Liner HDX vehicles manufactured February 19, 2008, through February 11, 2014, and equipped with Cummins Westport Model ISL G and Cummins Westport Model ISX12 G engines. Condensation in the intake manifold may freeze during cold weather conditions and interfere with the proper operation of the intake manifold pressure sensor.
The risk
The sensor malfunction could induce elevated exhaust temperatures or flames from the exhaust pipe, increasing the risk of a vehicle fire or burn injury to a person near the exhaust pipe.
The remedy
Cummins and Cummins Westport will notify owners, and authorized Cummins service facilities will upload a new ECM calibration, free of charge. The recall began on April 12, 2014. Customers may contact Daimler at 1-800-385-4357 or Cummins Inc. at 1-800-343-7357. Daimler's number for this recall is FL-660.
